HOSE-COUPLING.

Specication of Letters Patent.

Patented Mar. 1, 1921.

To all whom t may concern;

Beit known that I, ROY D. CRIPPEN a citizen of the United States, residing at an Die o, in the county of San Diego and State of alifornia, have invented certain new and useful Improvements in Hose-Couplings, of which the following is a specification.

My invention relates to a hose coupling more particularly adapted for use for coupling a hose to a pipe line for high pressure purposes such as air under pressure or steam and the objects of my invention are: first, to provide a coupling of this'class in which a very rigid coupling is made and which will not readily leak; second, to provide a coupling of this class wherein the hose is clamped to an insert member which provides a uniform pressure on the hose its full circumfere'nce; third, to provide a device of this class wherein. the hose is secured by means of a single clamp member provided with a plurality of ieible sections; fourth,r

to provide a device-of this class which is apsized hose and fifth, to provide a device o this class which is very simple and economical oi construction, durable, positive in its action, easy to install and which 'will not readily deteriorate or get out of order. r

W'th these and other objects in view as will appear hereinafter, my invention consists of certain novel features of construction, combination and arrangement of parts and portions as will be hereinafter `described inLdetail and particularly set forth in ther appended claims, reference being had to the accompanying drawingsand tothe characters of reference thereon which form -a part of this application,"in which:

Figure 1 is a longitudinal sectional view 'ofmy coupling complete shown with a fragmentary portion of a hose in position; Fig.

2 is a transverse sectional view through 2-2 ofFig. 1; Fig. 3 is an en'd view of the clam member; Fig. 4 is a longitudinal sectiona view thereof through 4--4 of Fig. 3; Fig. 5

is a longitudinal sectional view of the coupling in a slightly modified form from that of Figs. 1, 2,3' and 41:-` Fig.' 6 is a sectional view through 6 -6 'of `Fig. 5 and Fig. 7 isa longitudinal sectional view of the coupling in another slightly modified form Jfrom that of 1 to 6 inclusive Similarcharacters of reference refer to similar parts and portions throughout the several views of the drawings.

The insert member 1, clamp member 2, nut 3' and bushing 4 constitute the principal parts and portions of my hose coupling.

'The insert member 1 is provided with a hole lalongitudinally therethrough and the one end is provided withV a corrugated outer surface l". over which the hose A fits tightly.

It is provided with an outwardly extending flange 1 intermediate its ends and with a reduced portion 1'.l on one side thereof with another reduced portion 1" which is threaded at its outer end at 1f adapted to be fitted into a conducting pipe connection. Mount-4 edover one end of the hose A is the clamp member 2 which is adapted to t snug] on to the end of the hose and provided wit an inner corrugated surface 2. It is provided externally at one end with a, hexagon portion 2b and adjacentthereto with an annular groove 2. From said groove 2 to the small end it is tapered and providedwith an external thread 2. AIt is also provided with a pllurality of longitudinal slots, in this case I ave shown four', 2, 2', 25,Y and 2h, al-

"though there may be more if desired. In

the preferred form these slots extend only through the groove 2 from the small end j thus providing a plurality of iexible portions adapted to be clamped against thev outer surface of the hose. This member. 2 is forced over the end of the hose, then the hose with the member 2 is forced over the insert member l as shown best in Fig. 10fthe drawings. In order to secure the clamp member 2 therel is provided a nut 3 which is provided with "an internal tapered thread 3**I adapted 'to tit the thread 2d on the member 2.v

This nut 3 is also provided with an inwardlyl extending 'angeb which is adapted to fit over the reducedv rtion 1l and rest againstthe one side of t e ange 1 when screwed tightly on to the threaded end ofthe memf ber2 all as shown best in Fig. 1 of the drawings'. It will belnoted that when the nut 3 is screwed on to the iexible rtions of the member 2. they are presse inwardly against the hose the'slots 2, 2', 2, 2l Vand groove 2 permitting the flexible movement of the extendedthreaded portions of the member 2 lto readily move inwardly thus compressing the hose uniformly its full circumference depending onthe number of slots in the member 2. y

In the modified form of construction shown in Figs. and 6 ofthe drawings, the

l Fig. 7 of the drawings the construction is the samel as that shown in Fig. 1 except the internally extended flange 3b is eliminated so that-the nut may pass over the flange 1c and pass farther on to the member 2.

Though I have shown and described a particular construction, combination and arrangement of parts and portions and .certainmodiications thereof I do not wishto be limited to this particular construction, combination and 'arrangement nor to the l'modifications thereof but desire to include in the purview of my invention the construction, combination and arrangement substantially as set'forth in the appended claims. o

It isobvious that with this construction there is provided4 a coupling for connecting a hose to a conducting pipe line in which the hose is rigidly clamped in position; that the construction of the clamp member is such that the pressure is uniform around the' hose; that with this device the hose is easily installed in position and that the device is simple and economical of construction, durable and etlicient.

Having thus described my invention what I claim as new and desire to secure by Letf ters Patent, is:

1. In a coupling. of the class described, the combination with a hose, of a hollow insert member provided with an external thread on its one end and an extended hose insert portion at its otherend andv having an outwardly extending ange intermediate its ends, a` hollow clamping member provided with a plurality of longitudinal slots extending through the walls thereof and With an annular circumferential groove with which the end of some of said slots terminate and provided with an externally tapered thread on the slotted end and a nut provided with an internally tapered thread conforming tothe thread onA said clamp member adapted to be screwed onto the tapered thread on said clamp member.

2.*In a coupling of the class described,

the combination with a hose, of a hollow insert member provided ,with an external threadon its one end and a circumferentially corrugated external surface at its other end and having an outwardly extending flange intermediate its ends, a hollow clamping member provided, with a plurality of longitudinal slots extending through the walls thereof and with an annular circumferential groove with which the end of some of saidslots terminate and provided with an externally tapered thread on the slotted end and a nut provided with an internally tapered thread conforming to the thread on said clamp member adapted to be screwed on to the tapered thread on said clamp member,

` 3. vIn a coupling the combination wlth a hose, of a hollow inof thejclass described,

sert memberv provided with an external y thread on its one end and a circumferentially corrugated external surface at its other end and havingan outwardly extending flange intermediate its ends, a hollow clamping member provided with a plurality of longitudinal slots extending through the walls thereof and? with an annular circumferential groove with which the end of some of said slots terminate and provided with an externally tapered thread on the slotted end and provided on the one end thereof with means for holding it from turning, and a nut provided with an internally tapered .thread conforming to the thread on said clamp member adapted to be screwed on to the tapered thread on said clamp member. 1 l

In testimony whereof, I have hereunto set my hand at San Diego, California, this 23rd day of October, 1919.

ROY D. CRIPPEN.
